powerpc/mm/32: Fix pgtable_page_dtor call
Commit667416f385
("powerpc/mm: Fix kernel crash on page table free") added a call for pgtable_page_dtor in the rcu page table free routine. We missed the fact that for 32 bit platforms we did call the 'dtor' early. Drop the extra call for pgtable_page_dtor. We remove the call from __pte_free_tlb so that we do the page table free and 'dtor' call together. This should help when we switch these platforms to pte fragments. Fixes:667416f385
